GAR-VESTIBULE DIAPHRAGM.

Specification of Letters Patent.

Patented Feb. 112, rats.

To all whom it may concert Be it known that I, HARRY H. SoHRoYnn, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois have invented certain new and useful Improvements in GarVestibule Diaphragms; and I do hereby declare that the following is a full, clear, and ex.- act description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

A large majority of the vestibule diaphragms heretofore constructed have been made of fabric laid between the vestibule face plate and the end of the car in many different ways, so as to permit extension of the face plate with a consequent expansion of the diaphragm from the car end so that with cars coupled to one another a closed vestibule therebetween is always provided regardless of the position of the coupled cars. Where fabric or composition fabric has been used in the construction of flexible or. expandible diaphragms the fabric has always been laid with the warp of the fabric extending longitudinally of the diaphragm, so that in some instances a single strip of fabric has been used for the legs and top of the diaphragm.

It is an object therefore of this invention to construct a vestibule diaphragm wherein an improved arrangement of the fabric is provided to afford a structure a great deal stronger and more durable than similar types of diaphragms in which the fabric is connected with the warp disposed longitudinally between the frame members constituting the diaphragm.

It is also an object of this invention to construct a vestibule diaphragm wherein instead of laying the fabric with the warp thereof longitudinally of the diaphragm, the fabric is laid in sections with the warp of the fabric extending transversely or horizontally of the diaphragm, and with the respective sections stitched or riveted one to another.

It is furthermore an important object of this invention to construct a vestibule diaphragm made up of a plurality of sections of fabric arranged in overlapping relation with the warp of the fabric extending transversely of the diaphragm, permitting attachment of the edges of the respective sec tions one to another, thus providing a dia phragm of much greater strength than here tofore.

It is finally an object of this invention to improve the construction of vestibule diaphragms by a rearrangement of the fabric so that the warp thereof eXtends transversely instead of longitudinally of the diaphragm.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings:

Figure l is a side elevation of a vestibule diaphragm embodying the principles of my invention shown attached to the end of a car, only a fragmentary view of which is shown.

Fig. 2 is a section taken on line 2-2 of Fig. 1.

Fig. 3 is a sectional detail taken on line- 3--3 of Fig. 1, showing in enlarged detail the overlapped selvage edges and illustrating a modified means of connecting the fabric sections one to another.

Fig. l is a magnified plan view of a fragment of one of the fabric strips forming a part of the diaphragm.

As shown in the drawings:

The fragmentary end of the car is indi cated by the reference numeral 1, and attached thereto by means of a metal strip 2-, and bolts 8, is the expandible vestibule diae phragm, comprising a plurality of fabric sections stitched or riveted to one another, as desired, in overlapping relation. The fabric sections constituting the leg or side members of the diaphragm are denoted respectively by the reference numerals 4t, 5, and 6, and the top section of the diaphragm is denoted by the reference numeral 7, with curved shoulder pieces of fabric 8, secured to said top section 7, and also to the uppermost sections of the leg members. In each. instance the fabric sections are disposed and connected such that the wrap of the fabric extends horizontally or in other words transversely of the vertical diaphragn'i and not longitudinally therearound, as heretofore, where, for instance, a single continuous strip of fabric has been used for the purpose. The warp of the fabric is denoted by the reference numeral 13, and the woof by the reference numeral 14, with the selvage edges of the strips indicated by the reference numeral 15. Mounted on the outer end of the vestibule, and forming a part thereof is a. face plate 9, to which the ends of said fabric sections are secured by means of astrip of metal 10, and bolts 11, extending therethrough and secured into the face plate.

.As already stated, the respective fabric sections are'secured in overlapping relation to one another alongtheir selvage edges, and as clearly illustrated in Fig. 3, the sections may be attached to one another by means of rivets 12, although any suitable means for the purpose may be used.

The fabric is connected between the vestibule face plate 9, and the car 1, with the warp of the fabric denoted by the reference numeral 18, disposed horizontally, so that the selvage edges 15, of the fabric are riveted to one another.

I am aware that various details of construction may be varied through a wide range Without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted other wise than necessitated by the prior act.

I claim as my invention:

1. In a vestibule diaphragm of the class described a plurality of strips of fabric laid in overlapping relation to form the legs and topof the diaphragm with the Warp of the fabric extending transversely of the diaphragm.

- 2. In a vestibule diaphragm of the class described the combination with the top member thereof, of leg members connected thereto, said leg members comprising sections of fabric connected to one another with the Warp of the fabric extending transversely of the diaphragm.

3. In a vestibule diaphragm of the class described the combination with top and leg -members, of shoulder sections connecting said top and leg members to one another, the Warp of the fabric of said shoulder Copies of this patent may be obtained for five cents each, by addre'ssingthe Commissioner of Patents,

' ber thereof,

5. In a vestibule diaphragm of the class described top and leg members,- and shoul der pieces connecting the same one to another, the warp of the fabriccomprising said top members and shoulder pieces dis posed transversely of the [vestibule diaphra gm.

6. In a vestibule diaphragm of the class described, a plurality of strips'of fabric laid in overlapping relationto form the legs and top of the diaphragm, and with the selvage edges of therespective strips extending horizontally of the diaphragm and riveted to one" another. V .7

j 7. In a vestibule diaphragm of the class described, a plurality of strips of fabric laid in overlapping relation to form the legs and top of the diaphragm, with the selvage edges of the respective strips disposed horizontally for connection to one another. 7 v

8. In a vestibule diaphragm of the class described the combination with the topmem of leg members connected thereto said leg members comprising. sec-- tions of fabric connected to one another with the selvage edges of the fabric sections connected to one another and eXtending transversely of the diaphragm- In testimony whereof I have hereunto subscribed my name in the subscribing witnesses.
